185。 By 1914, ten of the western states had granted women the right to vote, but only one in the East.

(A) only one in the East

(B) only one eastern state

(C) in the East there was only one state

(D) in the East only one state did（E）

(E) only one in the East had

我选的是A。一定要把had不上吗。

我选的是A。一定要把had不上吗。

连词But后面的是个句子，动词一定要补出，根据时态选择使用do ,did, had来替代。

可以把but理解为副词性，表示仅仅，则b选项“only one eastern state”做同位语表示解释？？？

谢谢

我选了b

做同位语不太可能吧

没有和only one eastern state相同的概念
